Recent reports have implied that Rovers were set to send the Scottish striker to second-placed Derby County but Bowyer insists the 13-goal forward is going nowhere as the Lancashire outfit look to move into the top half of the Championship table.
"He's a valuable member of our squad. He scores goals," said Bowyer.
"We haven't given up hope of the play-offs ourselves so why would we want to even consider it?
"From a footballing point of view, we turned big money down for him in the summer so why we'd let him out on loan to potential rivals, I don't know.
"He does exactly what he says on the tin - scores goals. He contributes massively to our squad and we haven't got that many numbers anyway so we wouldn't want to be loaning anyone else out."
